Regarding to your claim to “who?”...
Not in Natural Sciences or Physical Sciences.
Physical Sciences involved in the following main branches:
- Physics
- Chemistry
- Earth Science
- Astronomy
Each of those branches, are multi-disciplines, with different fields and subfields.
Natural Sciences include everything in the above list for Physical Sciences, plus Life Science, which are multi-disciplines, eg biology, biochemistry, zoology, botany, evolution, genetics, etc.
But so that you would understand, here is the list of Natural Sciences:
- Physics
- Chemistry
- Earth Science
- Astronomy
- Life Science
In both Natural and Physical sciences, in order for concepts to be considered “science”, they must pass all 3 fundamental requirements:
- Falsifiability
- Scientific Method
- Peer Review
Social Sciences don’t need to follow the above criteria.
If you want to discuss or debate about WHO in sciences, then it might fall into one of the many branches, fields and subfields of Social Sciences.
Social Sciences involved in many areas, to wide to list them all, but here are the few that I can think at the top of my head:
- Psychology
- Sociology
- Anthropology (which also fall under Humanities)
- Archaeology (which also fall under Humanities)
- Political science
- Economics
And many more. They are involved the studies of human behavior, human cultures, and human activities.
Then there are non-science disciplines or studies, that fall under the broad branches, fields and subfields, which fall under the broad umbrella category: Humanities.
Humanities include the following:
- Languages
- Literature
- Art
- Music
- History
- Archaeology (which can under Social Sciences)
- Anthropology (which can under Social Sciences)
- Geography (human geography)
- Politics
- Law
- Ethics, moral
- Philosophies
- Religion (eg theology, comparative religions)
And many more.
Languages involved many fields, including philology, which is study of old written languages.
Humanities and Social Sciences related in some ways, like I have included archaeology and anthropology in both Social Sciences and Humanities. For instances, archaeology is multi-discipline studies, including translations of ancient inscriptions or literature, which would fall under the category of Languages, like the field in philology. So the part where archaeologists try to translate ancient texts involved philology, hence Humanities, not Social Science. It is the same with ancient or prehistoric objects discovered that involved artwork, eg painting, sculpture, etc, would make archaeology fall under the humanities category, not social science.
For all creationists, and some theists, who may not understand Natural Sciences so well. The theory of Evolution or Evolutionary Biology, like Natural Selection, Mutations, Genetic Drift, etc, is biology, but Social Darwinism has nothing to do with biology or with theory of Evolution.
Social Darwinism is a political and social ideology: Social Darwinism doesn’t even meet the requirements to fall under the Social Science category.
Like I said, Natural Sciences needs to meet certain criteria (eg Falsifiability, Scientific Method and Peer Review) to be considered science, but Social Sciences don’t, and Humanities are science at all.
And in Natural Sciences and Physical Sciences, they required evidence - physical evidence - that can observed/detected, quantified, measured and tested.
Can you measure God? Can you observe and test God?
If you answer “no” to the above questions, then
God or gods are irrelevant to science, when it come to studying biology or physical cosmology.
This is why the WHO questions is not asked in Physical Sciences or Natural Science, because something like god cannot be observed, measured and tested.
If you want to study God or anything pertaining to God, like religions or religious texts (eg Bible, Qur’an, the Book of the Dead, Veda, or any exegesis literature, etc), then try Theology or try Comparative Religion or Comparative Mythology.
